Melromarc brings a large fleet to fight the Wave out at sea. While the queen takes charge and leads the operation well, the other three heroes prove useless yet again, leaving Naofumi to do it all alone. Later, he gets help from L'arc and Therese to fend off the monsters, but then...
If a Wave attacks this place, 
the islanders will all die!
إذا هاجمتْ موجةٌ هذا المكان، فسيموت
كافّة سكّان الجزيرة
Wenn hier eine Welle eintrifft,
werden die Bewohner der Inseln …
Si viene una ola, la gente de la isla…
Si viene una ola, la gente de la isla…
Si une vague arrive ici,
les gens des îles vont…
Se un'Ondata dovesse colpire qui,
gli abitanti dell'isola...
Se a Onda atacar aqui,
os moradores da ilha morrerão!
Если Волна здесь ударит —
местные погибнут!
